ABSTRACT:
A refrigeration system for controlling airflow around an air-cooled heat generating device includes a variable speed compressor. The refrigeration system also includes evaporators positioned along a refrigerant line in a serial configuration with respect to each other and are positioned directly in at least one of the path of airflow supplied into the heat generating components and the path of airflow exhausted from the heat generated components. The refrigeration system further includes a controller and at least one temperature sensor. The temperature sensor is configured to transmit signals related to the detected temperature to the controller, and the controller is configured to vary the speed of the variable speed compressor based upon the signals received from the temperature sensor.
